Looking at the head porting guides, on the exhaust side, it is suggested to grind down the lumps around the valve guides in the ports to increase flow for boosted/top end applications. Nothing is mentioned about this on the intake side. I assume this is because doing so would hurt performance. Could someone explain to me why this would be so?

3100/3400, guess I forgot to mention that since I thought it could be inferred from the fact that those are the only heads on the site with a porting guide.
